Obama: NATO to Oppose Russian Aggression

Confronted by a Kremlin-backed military offensive in Ukraine, President Barack Obama and Western allies will approve plans this week to position at least 4,000 troops and military equipment in Eastern Europe, bolstering NATO's security commitments to nervous member states near the Russian border. In a speech in Tallinn, Obama said the vision of a Europe dedicated to peace and freedom is "threatened by Russia's aggression against Ukraine," but said NATO will not allow that aggression to go unchecked. "We will defend our NATO allies, and that means every ally," he said. "We will be here for Estonia. ... You lost your independence once before. With NATO, you will never lose it again."
